Drowning In Regrets

Today was one of Eren's very, very rare off days, and normally he would want to spend it with his friends. Laughing, joking, playing around with whomever he could, or he would spend it in the library Armin had showed to him, reading the hundreds of books pertaining to the outside, behind the walls. Of the ocean and whatnot since he obtained an intrest of it because of his blonde friend.

It may not seem like it since he puts on a strong front, but secretly the brunette blames himself for everything that's gone wrong in his life, from his mother's death to failing to capture Annie due to his hesitation. He's always blamed himself for being unable to do things properly.

Today was just one of those days where his past mistakes had hit him especially hard, and because he didn't want any of his closest friends thinking any less of him because of his own doubts, he decided it would be best to keep to himself in his own room.

Will he be able to cope with his emotions alone by himself or will he drown in his regrets?
